Abstract (en)
[origin: US6983182B2] A contrast enhanced dynamic study of a subject is performed with a CT system. A series of undersampled image data sets are acquired during the study with successive data sets acquired at interleaved projection angles. More fully sampled image data sets are formed by transforming the x-ray attenuation projection data to k-space and then sharing peripheral k-space data between undersampled k-space data sets. Artifacts due to undersampling are thus reduced without significantly affecting the time resolution of a series of reconstructed images.
